Shimano knew that the Ultegra 6800 cassette would reside as the heart of the new 11-speed system, which is why it devoted considerable time on a feature known as 'rider-tuning.' What this means is that you receive an updated range of useable gearing options with the advent of the 11-speed design.

Cassette options with Ultegra 6800 now range from 11-23 to its climber-friendly 11-32. The additional cog in the back means the new cassette runs straight through for a bit longer, which generally means the addition of an 18T cog over the 10-speed. This smoother run of gearing is most noticeable while spinning in the top end of the block, allowing more consistency and control over your cadence compared to 10-speed cassettes.

Shimano Ultegra CS-6800 Cassette is slightly lighter than its 6700 brother, and it does a nice job of closing the gap on Dura-Ace 9000. The tallest cogs are riveted onto an aluminum carrier for weight savings, and they're gentler on aluminum cassette bodies. Shimano improved its manufacturing quality too; now they can make the ramps stronger because they can build to tighter tolerances. And the ramps themselves have been revised for faster shifting.

The Ultegra CS-6800 Cassette has 11 cogs and comes in the following ratios: 11-23T, 11-25T, 12-25T, 11-28T, and 11-32T. Each cassette wears a nice chrome finish and comes with an alloy lock ring. Please note that the CS-6800 is recommended to be paired with corresponding Ultegra 6800 components.

The Ultegra 6800 cassette is a thing of beauty that gets beat up and abused more than anything else on your drive train. It gets forgotten in the back because when everything else works, you don't need to worry about the cassette. Wipe it down when you clean your chain and replace as needed based on wear.

I currently run a 105 52/36 set up up front and a 12/30 in the rear cassette Ultegra. Would there be issues if I run the 11/32? I already have a longer cage (Ultegra)...

Great cassette for any 11 Speed setup

  • Familiarity: I've put it through the wringer

I built up a SRAM Force/Rival/Red setup for my commuter and used the ultegra cassette and chain for the package and the thing shifts perfectly. The ultegra cassettes seem to last me about 3-4 chains. Each chain replaced at around 1500 miles or when it reaches just over .5%.
I am using a red crank, Force 22 shifters, force 22 FD, and Rival 22 RD.

Also worth the weight!

    Like all of the Ultegra 6800 group parts, the Ultegra cassette works flawlessly, won't make you have to skip a mortgage payment and will cost about 40grams. The way I see it, unless you're getting a paycheck for pedaling your bike you'll sweat off the 40 grams while enjoying the super-smooth, predictable shifting this cassette provides!

    SHIMANO has done it once again

    • Familiarity: I've put it through the wringer

    This cassette is fantastic. Shifting is effortless, like slicing warm butter. Each gear hits right on the mark even with tension out of the seat climbing, no miss shifts.

    I upgraded my 8 speed drive train with a triple up front to the whole 6800 group set... Love SHIMANO

    Best road cassette for the money

    • Familiarity: I've used it several times

    The Ultegra is the best cassette out there for the money. I replaced the 12-25 that came on my new bike because I do a lot of climbing and needed some easier gears to spin. I first used this for a century ride in which I climbed nearly 7,000 feet and I didn't miss a shift. Love it!

    The best cassette

    • Familiarity: I've put it through the wringer

    I'm running this with my DA9000 setup and it works flawlessly. Why not run a DA you ask? well I don't like spending that much more money to save a couple grams and the ultegra just last way longer.

    • Familiarity: I've put it through the wringer

    While not as light as Dura Ace, the Ultegra cassette offers smooth shifting and long durability at a reasonable price tag. Unless you are counting every gram or have a Dura Ace tattoo somewhere on your body, your cassette search ends here.

    I have dura ace di2 with a 11/28 cassette and 52/36 up front...its hard on long big climbs, can i change the cassette for this 11/32? is it compatible? will i sacrifice the quality of the durance di2?

    If you have the dura ace di2 RD-9070 rear derailleur, unfortunately no. You need a medium cage rear derailleur to use the 11/32 cassette. I'd recommend considering switching to a compact crank instead - like the FC-9000 50/34

    There is a work around, flip the b-tension screw and you can go up to 32. Ssshhh don't tell shimano.

    IT WORKS!

    • Familiarity: I've used it several times

    No big shocker, but it works! Had to upgrade from a 10 speed freehub body on this older wheelset when I got the 105 5800 group. Works like it's always been this way, good cassette!

    It's a cassette

    • Familiarity: I've put it through the wringer

    What can you say? It is a cassette. Shimano makes good stuff. This is nice. Not the lightest, but it gets the job done and done well. I am using the 11x25 11 spd version of this on my 2nd wheelset.

    11-speed. Great for climbing and all-around training. It doesn't wear out as quick as the DA versions

    Can you use the 11-32t cassette with the short cage derailleur?

    Best Answer

    RUBP438210,



    No, you would need the Mid/Long cage derailleur if you wanted to use the 11-32t cassette. The short cage is designed to only have enough chain wrap for a 28t or less cassette.

    i use an 11-32 with a short, however, you CANNOT cross chain in your big ring (to your 32).

    i have no problems with my small ring to my 32.

    i only have this setup on my training wheels, and pay strict attention so that i do not cross chain.

    if i have to be in my 32 i should be in my small ring anyways.

    it is not the ideal setup, however it does work - you might have to adjust your b-screw.

    I have Shimano Ultegra 6800 11-speed short cage on my 2015 CAAD 10. I have the 11-32 cassette on my CK/HED climbing wheels and it works like a dream. A fellow rider has been running this CR-Cassette combo for three years with NO PROBLEM. I just don't use large CR to 32.

    Superb cassette and light :)

    • Familiarity: I've put it through the wringer

    Always superb quality, weight is dead-on at 212gm for the 11/23. I also have a DuraAce 9000 and will use this one for flats and daily riding, putting the 11/28 9000 series on my climbing wheels. For those using Shimano cassettes and note that some freehub bodies are prone to indents from the DuraAce cassettes - using Ultegra cassetes will always solve that problem, as the titanium cogs on the DuraAce are just too hard. Sticking with the Ultegra, especially at this price, is a total no brainer. Shifting is solid and dead on, no skips or hesitations and quiet as can be :) Also noted that I have tried Zipp and Mavic wheels with both the Ultegra and DuraAce 11-speed cassettes and have not had any scoring/indents on the freehub bodies; even after 3000 miles. Looks like the newer 11-speed freehubs are hardened (at least for these two manufacturers) - so cheers to that!

    Superb cassette and light :)

    Do you need any spacer for ZIPP 2014 404 wheel? I mean on older version of mavic there had to be spacer first and than 10speed cassette. Now do you need spacer for new 11speed zipp wheel with 11speed cs-6800? (spacer woud go on the freehub body first ant than the cassette itself)



    Thanks for info.

    Greetings - No need for the spacer on the new Zipps ;) For the Mavics, just remove that specific washer/spacer, and 11-speed will work as well :) Note, all the new 11-speed drivetrains use the same spacing, so now you can use any 11-speed cassette with any drivetrain - like a mutt ;)

    Can the CS-6800 be used on the Shimano...

    Can the CS-6800 be used on the Shimano version of the PowerTap G3? I'm using this hub with CS-6600 right now.

    Best Answer

    greetings - You should be good to go :) See the link to the actual PowerTap website for that tasty hub. Good day :)

    http://www.powertap.com/collections/hubs/products/powertap-g3-hub

    Unfortunately, I found that the CS-6800 doesn't fit my Shimano PowerTap G3. I'm trying to buy a replacement 11-speed freewheel body for it. My understanding is that this freewheel body will not require re-dishing my wheel and will allow me to mount the CS-6800 ... and therefore upgrade to Ultegra 6800 throughput.



    Maybe DRZIPGRIP is thinking of newer versions of the G3 hub, but mine certainly does not accommodate this cassette.

    Mike, I just replaced the freehub body in my G3 with the 11 speed version and it is a piece of cake. It will allow you to run a 10 speed cassette (with a spacer) and the 11 speed cassette without. It just pulls right out of the hub and you slide the new one in.



    Cheers.

    It's a piece of cake if you have a compatible PowerTap hub; some PowerTaps can't accept the 11-speed body. (And, even if it does, it's about $90 to buy the new hub.)

    Sorry, amateur question, can the 6800 be dropped in place of an existing 10sp 6700 gear set, or does the full set need to be upgraded as well?

    I would think that you'd have to switch out the shifters for sure to get the 11th gear, but the rear derailleur is probably still ok from the 6700.

    Best Answer

    Additionally, wheel manufactures are still catching up to the 11-speed. Currently the Shimano 9000 line of wheels with work, also, Most Mavic wheels will work with 11-speed, even some older models. New Zipp's will work. Just make sure that the wheelset you are using is compatible - hope it is :)
